The current (cvs) version of MIDAS should build on Mac OS X right out of the
box- I fixed all the problems you report back in February(?)- see the macosx
thread in this forum. A few weeks ago I verified that it still compiles on Mac
OS 10.3.4. The Mac OS port received minimal testing- I checked that "odbedit"
and "mhttpd" run, that's about it. K.O.

The tar package is only done for a new release (which will happen in the next days
BTW), so http://midas.psi.ch/download/tar/ contains the most recent packages. Upon
request I make a midas-snapshot.tar.gz, but since there will be a 1.9.4 soon, it's
maybe not necessary right now.

Unfortunately, I still encounter the same problem.

What does '-rpath' mean? It is just a linking error. Thanks.

Fixed. Good catch.

> What does '-rpath' mean?

You will have to read the "ld" manual. In the nutshell, it tells the executable where to look for shared libraries. 
Aparently it is not supported by Mac OS X.

I use:

setenv CVS_RSH ssh
cvs -d cvs@midas.psi.ch:/usr/local/cvsroot checkout midas

It works most of the time. Sometimes I get locking and "permission denied"
errors on some subdirectories, presumably when CVS is being reorganized or
when there are stale locks. Does not happen too often.

Hi,
 I am really puzzled: I am running the very same as far as sources
are concerned (Dec 12, 2003 snapsot) midas frontend (miniexp + camacnul)
on two different machines (and the same trusted private network):

1) one is an ancient Pentium/100 MHz laptop with RedHat Linux 7.3 and 
2) another one is event more ancient MVME167 25MHz running VxWorks 5.4.2

The front end on my Linux PC works just fine, whereas on the MVME167
I get intermittent crashes (most often at the end of the run).
[Correction: the crashes happen, I think, when the frontend wants 
to update the ODB]

The crashes happen in db_set_record routines

Any ideas what might be wrong? 
Except that MVME167 is a piece of ...#@!% 

Piotr

A followup: I traced back the problem to version 1.9.2.

Version 1.9.1 does not have this problem but 1.9.2 does. 
For now I stick with 1.9.1

Piotr
 

Starting from midas version 1.9.4 on, the environment variable 'MIDASSYS'
should be defined and point to the installation directory of midas. The
purpose of that is that add-on packages (like the upcoming ROME system) can
find the midas libraries and include files. It is excatly the same as for
ROOT which defines ROOTSYS and should therefore be straight forward. The
libraries should then reside in $MIDASSYS/lib (or %MIDASSYS%\lib under windows).

To remind users about this new variable, a test has been added to odbedit,
which shows a warning when starting odbedit and MIDASSYS is not defined.

Version 1.9.4 of midas has been released today. It is mainly a maintenance
update, for all the little things which have been fixed since the last
release, and does not contain major new functionality.

1. Finally! It's about time to do that! 

2. What will the entire structure tree look like?

Here's my suggestion
MIDASSYS=/opt/midas-1.9.4 (for example)   


so the Linux binaries would go to 
MIDASHOST=i386-pc-linux-gnu
$MIDASSYS/$MIDASHOST/bin
$MIDASSYS/$MIDASHOST/lib

the VxWorks binaries
MIDASHOST=m68k-wrs-vxworks
$MIDASSYS/$MIDASHOST/bin
$MIDASSYS/$MIDASHOST/lib

and the shared stuff would go to 
$MIDASSYS/include
$MIDASSYS/share/drivers
$MIDASSYS/share/examples

The Makefile would need to be adjusted (for make install) but that is not
too complicated

What do you think?

Regards
  Piotr

I guess we should follow the "standard" as much as possible. MIDASSYS was inspired by
ROOTSYS. Now where do people usually install ROOT? Is it /opt/root-x.x.x or something
else. Some years ago (when I did the last time some linux administration) optional
packages were put into /usr/local by default. I guess you have more experience with
today's tradition, so do whatever you thing is standard.

> so the Linux binaries would go to

Does that mean that the path has to be modified to include $MIDASSYS/$MIDASHOST/bin?
If we put a link to /usr/local/bin, the path does not have to be modified. What about
shared libraries? Does ldconfig know about /usr/local/lib, or $MIDASYS/$MIDASHOST/lib?

> and the shared stuff would go to

What about /usr/share? Is that a common place for documentatino etc?

Thanks for your advice.

I agree that we should follow the standard. 
I used /opt as an example. 
There are several "schools" as to where put things my philosophy is
/usr/{bin,lib,include}       - std OS packages (RPMS, .deb or whatever your flavor likes)
/usr/local/{bin,lib,include} - make/make install packages
/opt/..                      - additional packages (RPMS, ...) 

But it should be up to the user what $MIDASSYS she/he likes.

The path could/should be modified in users .bashrc/.tcshrc or we could provide a simple
system-wide script(s) that would do the job.
For years, I've been using such a scenario on my Linux PCs with regards to various
add-on packages (e.g. cern). 

Here's an example of my cern.sh that goes into /etc/profile.d on my RedHat Linux PC
#===================================
. /etc/profile.d/.functions
export CERN=/cern
export CERN_LEVEL=pro
addpath $CERN/$CERN_LEVEL/bin
#===================================

As for library path: there are several ways (as with exec path)
a) nice way: modify /etc/ld.so.conf by adding $MIDASYS/$MIDASHOST/lib
b) modifying LD_LIBRARY_PATH (there's some security issues with it)
c) symlinking to /usr/local/lib


>

Yes. Check any recent Linux distribution /usr/share is full of docs, icons, etc.

This is my bias. 

I (obviously) prefer packing things into rpm which makes install/updates 
very easy - especially if you are managing several machines.

For a long time the "de facto" standard was to spread a package around in many
directories under /usr/local.  This proved to be a bad idea, as removing the
package
became very difficult.

With POSIX there is a written standard, which says that each pacakge goes in
it's own
directory under /opt. eg. /opt/midas.  Each package gets to define it's own
structure
within that directory.  One could imagine several versions installed at the
same time
/opt/midas/v1.9.2 and /opt/midas/v1.9.4 each with a bin, lib include etc. 
Following the
ROOT example, you could make a link from /opt/midas/pro to
/opt/midas/v1.9.4, so that
system files and login files are easy to maintain etc.  The basic idea is

MIDASSYS=/opt/midas/pro
PATH=$PATH:$MIDASSYS/bin

though a more sophisticated approach is

MIDASSYS=/opt/midas/pro
echo $PATH | grep -q $MIDASSYS || PATH=$PATH:$MIDASSYS/bin

where the assignment line (Bourne shell, and BASH shell) ensures
that multiple entries are not added on the PATH even if the script is more
than once.

POSIX also goes on to say that links from /opt/bin can be made if desired. 
I find this
usefull if a package has only one or two executables, and I don't to make
multiple
versions available.

I hope that the POSIX ideas are usefull,

John.

That sounds all very good to me. So can you please sit together (at least John,
Piotr, and Pierre-Andre), discuss a common scheme and and propose it officially in
this forum for comments. After a week or so, it should be implemented into the
Makefile and installation scripts. I also would like to have Paul Knowles giving
it a look, since he voluteered to make the midas RPMs, which also heavily depends
on the chosen directory structure.

I have compiled the sources on Darwin 7.4.0 with gcc 3.3. After the compilation of source codes, I 
try to execute "gmake install". I got the following message:
-------
Nothing to be done for "install".
-------

The install target could not be executed. Then I add the following line to the Makefile:
------
.PHONY: install
------

The install target can be executed. But when it is tring to copy "dio" to the proper directory, it 
cannot find the file. Then I found that the "utils" target isn't built. 
I try to build the target: darwin/bin/dio, I got the following error:
-------
cc -g -O2 -Wall -Iinclude -Idrivers -Ldarwin/lib -DINCLUDE_FTPLIB   -DOS_LINUX -DOS_DARWIN 
-DHAVE_STRLCPY -fPIC -Wno-unused-function -o darwin/bin/dio utils/dio.c
utils/dio.c:39:20: sys/io.h: No such file or directory
utils/dio.c: In function `main':
utils/dio.c:46: warning: implicit declaration of function `iopl'
gmake: *** [darwin/bin/dio] Error 1
--------
So, the include file "sys/io.h" may be changed under Darwin. I don't know how. I will try later. I 
hope somebody can notice this. 
Best regards.

There are not such a file "io.h" inside my MacOS X. In fact, I didn't find any file containing function iopl().
So what is the equivalent function of iopl() under MacOS X? The utility dio should be modified in order to be compiled under Darwin-
gcc platform.

"dio" is not supported under MacOSX. It is used to grant user programs access to PCI and ISA cards (usually CAMAC interfaces). We have
no MacOSX hardware with PCI or ISA slots so we cannot test and support this functionality.

The MacOSX Makefile should not try to build "dio". I will accept a patch to fix this Makefile bug.
